REVOLUTION-INDICATING MECHANISM FOR SPINNING-MACHINES.

Specification of Letters Patent.

Patented Feb. 25, 1908.

Application filed October 22- 1903. Serial No. 178.066.

' T all whom a may concern:

' Be it known-that I, LYMAN O. GoonwrN,

a citizen'of the United States, residing at- North- Andov'e'r, in the county of Essex and State of Massachusetts, have invented an Improvement in Revolution Indicating Mechanism for Spinning-Machines, of which the following description, in connection with the. accom an in drawings, is a specification, like letters on the ing like parts. v

Spinning machines, a variety of which is drawings representinstanced in the mule, employ what is known the textile art as time whe'el mechsnis'm, said mechanism being provided for I determinin usuall-- a certain number of rotations of parts the machine,- or periods during which certain parts may operate with relation to other-parts of the'machine.

l have herein shown my invention as oooperating' with a worm deriving its motion from'th'e main or driving shaft of the mule,

. such for instance as represented in United tion, to enab States 'Pittent No. 272,401, February 20,-

1883, and to indicate the amount of twist being put'into the yarn. The devices herein shown are, however, applicable to roving,

, drawing and other rollers or shafts employed iii-spinning machines of which the mule 1s a Trier to my invention in all the time Wheel or revolution indicating mechanism so far as I am aware, the worm-toothed wheel of such mechanism is carried by a sliding-- frame and is intrrmittingly engaged with a worm on a drivei shaft, but herein I have mounted said wheel on a stud stationary with the frame, and hi e provided for the constant engagement of'the worm-toothed wheel with its actuating worm, and said wheel which is moved constantly during 'the operation of the machine ,conswitutes driving means for the indicator or time-wheel, the latter term being the technical designation thereof.

1 Figurel in elevation looking at the end of the inule behind the head shows a sufficient portion of, a mule with my improvements added, some arts of which are shown in sec:

le the same to be understood; Fig. 1 a detail showin part of the ed e of the indicator wheel wit the dog held t ereon a's in Fig. 1; Fig. 2 is a ri ht hand viewof the parts shown in-Fi'g. 1, with the exception that constitutes a handiece that the stand and lever forming part of the clutch closing means are omitted and the dog 22 removed; Fig. 3 shows in side eleva tion and end view the clutch sleeve removed from the indicator wheel; Fig. 4 shows detached the upper art of the lever; Fig. 5 shows an edge and ace view of the hub ofthe worm-toothed wheel O Fig. 6 in .two views shows the dog 22 detached, and Fig. 7 shows the lever 24, 25 detached.

Referring to the drawings, A re resents art of the head of a mule to which is bolted 'y suitable bolts A a guideway A grooved at one side to receive and guide a slidingframe A provided with a cam A constituting the moving device for the clutch-closing means to be described. This sliding-frame fitted to be moved vertically in the guideway A by the usual gear having a cam-roll and deriving its motion from the drawing-in shaft as in said patent, has a rojection A y which to lift the sliding-frame w en desired. The

sliding-frame also sustains a bolt A on which is pivoted a locking-device A made as a hook that when engaged with a projection A extended from a bracket A secured to the guideway A, by bolts A, as in Fig. 1, or it may be to the head of the mule, locks the sliding-frame in its operative position.

The locking-device or hook A at its up er end has a pin a, and a spring a surroun s a bolt a fixed tothe cam A extended loosely through a hole in a In a on the hook A the s ring acting norma ly to cause said lookingevlce, Whenever the shding-frame 1s lifted in usual manner during the operation '90 of the mule, to engage the projection A The head has a depending bracket C which acts with the guideway to sustain the op 0- site ends of a stud C shaped as best shown full lines Fig. 1, said stud being held fixedly in position by nuts I), b, a plied thereto at its 0 posite ends. The stu has a shoulder 5 w ich abuts against a boss 8 of the guideway, and said stud also has another shoulder against which is received a washer 9 that loosely surrounds the stud and furnishes a seat for one end of a cushionin 'spring'IO which also surrounds the ,stud and is received between said washer and thc'boss 8 I The stud has applied to it loosely next said washer a worm-toothed wheel 0 that constithe yarn, and is stopped after the worm-wheel O has aseries of clutch-teeth 12;

see Figs. 1 and 5.\

The hub of the indicator-wheel C at its right hand side has an extension shown as provided with a flange 13 with which is connected a ro e 14 to which is attached in practice a weig t, not shown, which serves to revolve the indicator-wheel backwardly into its starting position after each complete operation thereof, and after the descent of the sliding-frame, which takes place once during each cycle of operationsof the member or part of the spinning machine or mule with which said indicatorwheel is arranged to cooperate, and as herein illustrated it is understood that the indicator-wheel is moved during the time that the-twist is being put into redetermined'amount of twis has been reac ed.

Surrounding the stud C is va collar 7 which abuts a shoulder formed in the right-hand side of the hub of the worm-wheel C as best seen in Fig. 1, and resting against said collar is one end of a spiral spring 15, the outer or right-hand end .ofiwhich abuts a washer 16 located within a chamber of a clutch member or sleeve C see Fig. 1, saidclutch having teeth 12 that co=act with the clutch-teeth 12of the wheel C said toothed parts constituting the clutch for coupling the indicator- Wheel to the worm-toothed wheel whenever it is desired that the continuously moving actuator shall pick up and rotate the indicator-wheel for substantially a full rotation .pin hasbeen carried by a worm-wheel, and it or less, that-the indicator-wheel may. act and fulfil the purpose re 'uired of it. The spiral s ring 15 whenever ee 'to act so moves the c utch part referred tees to permit the wheel C to continue its rotation and not affect the indicator-wheel. Part of the sleeve C? carrying the clutch-teeth is extendedas shown at 1-7, nearly to the outer end of the hub of the indicator-wheel, which latter abuts a etc 18 at the inside of the bracket C.

The lower end of the bracket C has an opening in which is located a bolt 19'on the extremities of which is ivoted a forked lever C having an adjustab e arm C The forked end of the lever contacts with the outer end of'the clutch sleeve C and the arm C is acted upon by the cam A before described carried by the. sliding-frame, whenever said frame is lifted in the usual manner by or through the roller-carrying gear driven by the drawing-in shaft, causing said lever to move the clutch sleeve C to the left preparatory to clutching the indicator-wheel operatively with the continuously moving actuator C The lever and cam constitute one form of what I shall hereinafter designate clutch actuating means, they being represented in positionto effect the clutching of the-indi-' ened so that through-the inclined edge of the cam A the forkedend of the-lever may be made to contact just as required with the outer end 17 of the clutch sleeve C;

' The indicator-wheel has extended entirely aboutits edge a series of holes 20 in anyone of which may be entered a pin 21 carried by a dog 22, having a backward rejection 220,

said dog embracing the edge 0 the indicatorwheel, and the pinconnectin the dog with any hole ofthe indicator-whee The adjustment of the dog on the indicator-wheel by placing the pin 21 in any preferred hole 20 provides for variations in the extentof the.

twist to be put intothe yarn, or provides for any desired number of holes of twist, or provides for the rotation. of the indicatorwheel for a definite period before the indicator-wheel will be d1sconnected fromits driving means.

The indicator-wheel has upon its face an 'index line for each hole 20, and as shown there are seventy-fivelines divided in groupsof five, and the grou s are numbered from v zero to 751 By num e ring the face of the wheel as illustrated instead of marking the wheel with a number next each hole 20, it is possible to more readily read the number on the wheel by looking at the pin, the latter lining with one or theother-of the marks, in-

stead of looking for the'number next the hole,

some of which numbers at times will-be covered by 'the'dog 22.

Heretofore in this class of apparatus the has been customary. to determine by actual count the number of the hole inthe wormwheel in which the pin was to be placed to provide for turning the worm-Wheel for the desired length oftime before the worm-wheelwas disconnected from its driving means. In this my invention by reason of the index 7 sired period, or until the desirednumber of holes of twist have been gained.

, The face of the indicator-wheel has a pin 23 that when the indicator-wheel is to be started occupies a position at the right,see'Fig. 2, of and contacts with an arm 24 depending from a collar 25, lo'osely surrounding the inner end of the clutch sleeve C", the lower end of said arm atsuch time being represented as interposed between the projection A and the pin a of the locking-device A said pin 23 by contact with said arm, as the rope and weight described act to turn the indicator-wheel in a smearas direction opposite the arrow, Fig. 2, arrests the indicator-wheel in its normalor starting position. V

Now, as the indicator-wheel surrounding the ciutch sleeve C and operatively engaged with the wheel C is rotated in the direction of the arrow, Fig. 2, the projection 220 of the dog 22 finally meets the left-hand side ofthe arm 24 and turns said arm to the right from I the position Fig. 2, causing the extremity of said arm in contact with pin a to turn the locking-device aside from its engagement with the projection A and thereafter a spring at, partially shown and connected at one end with said sliding-frame and at its lower end to some fixed spot, depresses the sliding-frame and its cam A, the latter retire ing from its contact with the lower end C of the lever C. As soon as this happens the sprin 15 immediately expands and moves the clutch sleeve to the right, disengaging its teeth from the clutch teeth 12 of the wormtoothed wheel C and turning the lever C on its fulcrum until said lever meets a stop (1 When the sliding-frame is again lifted in 'usual manner, as before stated, by or through the drawing-in shaft, the cam A" meets the lower end of the lever C" and turns said lever to thereby move to the left, viewing Fig. 1,

the clutch sleeve C causing it to engage the clutch teeth 12 of the worm-toothed wheel, and thereafter said wheel immediately takes u and rotates in unison with it the indicatorw eel, turning the latter until the projection 220 again through the arm 24 disengages the locking-device and permits the descent of the sliding-frame. Herein it will be understood that the teeth of the Worm-toothed wheel C are always in mesh with the constantly movag: ing driving device represented as the usual Worm?) fast on a shaft D- liaving a bevel pinion D that is engaged by abevel inion I) on the main driving or power shaft 7 of the ma chine.

It will be'unders'tood that different parts of a spinning machine and especially of a mule have to beturned for a definite number of revolutions, such for instance as the roving rollers, and drawingrollers, and revolution indicating-wheel mechanism substantially such as herein described is applicable not only to 1 determine the extent of twist, but also the number of rotations of said rollers.

Heretoi'ore, as stated, the worm-toothed wheel has been driven intermittingly by a the worm-teeth go into mesh with the teeth of the worm to thereby prevent damage of parts 111 case of fault in mesh.

is moved substantially continuously during 7 the operation of the machine; and also the first drive an indicator-wheel through a -clutch from a continuously rotating actuator, and I desire to claim these features broadly, as the parts shown in carrying out my invention in one of the best forms now known to me, nught be changed in shape and be variously modified and yet include the gist-of my invention. which is defined in the claims hereinafter presented.

I also believe that I am the first to rovide an indicator-Wheel having a series 0 holes, either of which may receive the twist pin, with graduations to indicate instantly to the eye the number of holes of twist.
